Question 1

What is Mobile Device Management (MDM) and what is its primary purpose?

Accepted Answer

A solution that allows organizations to remotely manage, monitor, and secure employee mobile devices

Answer

MDM solutions enable organizations to enforce security policies, manage applications, and remotely monitor and control mobile devices used for work purposes.

Question 2

What security risk is associated with outdated firmware on IoT devices?

Accepted Answer

Unpatched vulnerabilities in old firmware can be exploited by attackers to compromise the device and potentially the entire network

Answer

IoT devices running outdated firmware contain known, unpatched vulnerabilities that attackers can exploit to gain unauthorized access, compromising both the device and the broader network.

Question 3

What is jailbreaking or rooting a mobile device and why does it increase security risk?

Accepted Answer

Removing built-in security restrictions to gain full system access, which also removes protections against malware and unauthorized access

Answer

Jailbreaking (iOS) or rooting (Android) removes manufacturer-imposed security restrictions, allowing more customization but also eliminating critical security safeguards that protect against malware and unauthorized access.

Question 4

What is an IoT botnet and how are such botnets typically formed?

Accepted Answer

A network of compromised IoT devices controlled by an attacker, typically formed by exploiting default credentials and unpatched vulnerabilities

Answer

IoT botnets consist of large numbers of compromised IoT devices (cameras, routers, smart appliances) that have been infected with malware and can be centrally controlled to launch attacks like DDoS.

Question 5

What is the security benefit of network segmentation for IoT devices?

Accepted Answer

It isolates IoT devices on a separate network segment, limiting an attacker's ability to reach critical systems if an IoT device is compromised

Answer

Network segmentation places IoT devices on a separate network, so if an IoT device is compromised, the attacker cannot easily access computers, servers, and sensitive data on the main network.
